Did this reboot loop occur following some physical impact or contact with water or did it just happen out of the blue? Was this iPad previously repaired?

You said after cleaning the port and tightening the screw that the battery was pulling current. Is that because you have it connected to a USB ammeter? If so, what current was it pulling?

Sorry for all the questions but the more info you share, the more directed my answer.

It is entirely possible that the battery is just dead or dying and not charging properly. It could be a defective charge port (check the internal pins under magnification) or it could be a defective charge circuit (caused when using cheapo chargers and cables) .
